TSA: Houston fliers rank high for seized carry-on weapons at airports

More than half a dozen loaded guns have been seized in the past 30 days from passengers trying to bring them through security at Houston's airports, according to the Transportation Security Administration.

The stats build upon previous figures released by the TSA, which put Houston in the top three in the nation for guns seized at airports.

Two loaded 9mm handguns and three .380's were pulled out of hand luggage at George Bush Intercontintal Airport in the first week of July. Another loaded 9mm and an unloaded .45 were found this past week, along with a loaded .380 at William P. Hobby Airport.

In total 75 guns have been seized from U.S. airports so far this month.

The firearms join countless prohibited items passengers attempted to bring through security check points all over the country. The TSA has released pictures of many via its online blog.

Headlines include a canister of bear repellant, essential in any flying situation, and many, many "sharp pointy things" according to officials.

Officials also revocered a vaporizer (i.e. bong) shaped like a grenade, and a pair of knives shaped like a gun and bullet – not the stealthiest of decoy items one could pick for sneaking an item past TSA.

One passenger in Honolulu, Hawaii tried to board a plane with a decoy improvised explosive decise (IED) he claimed was used for bomb disposal training.

Seventy-four credit card knives were seized across the country as well as much larger knives disguised in luggage and in clothing. One was a knife concealed in a Scooby-Doo greetings card.

A knife was found hidden in a shoe at Detroit Metropolitan airport. Knives concealed as combs were found there and at Kansas City's airport.

Among the ceremonial weapons seized was a sword at Columbus International Airport and a pair of ninja sais recovered at Chicago's Midway airport.

The TSA also says, despite warnings, some passengers continue to bring fake grenades in their hand luggage, which are just as prohibited as real grenades.

Twenty nine stun guns and stun cane were also found as well as fireworks.
